Definitions

  • the present invention relates to a heat transmission tube, and more specifically to that built in an evaporator of a freezer, a coolant being boiled at the outer surface of which when the tube is used.
  • the heat transmission tube disclosed in Published Unexamined Japanese Patent Application (PUJPA) No. 57-131992 can be named as a typical conventional tube which boils coolant brought into contact with the outer surface thereof through exchange of heat between the coolant and fluid in the tube, so as to enhance transmission of heat propagated on to coolant (to be called boiling heat transmission hereinafter).
  • a heat transmission tube is characterized by having a first and second groove portion formed on the outer surface of the low-fin tube by a roll forming process.
  • This type of heat transmission tube is used in a liquid or gaseous coolant.
  • This tube exhibits a good property in terms of heat transmission rate since, in the tube, bubbles remaining in the groove make boiling continue, thereby increasing the amount of heat transmission. Thus, a high transmissibility can be achieved.
  • the purpose of the invention is to provide a heat transmission tube which exhibits a high and stable heat transmissibility in both cases of low and high heat fluxes.
  • a heat transmission tube having a tube body, first grooves formed at a predetermined pitch therebetween on an outer surface of the tube body continuously along a circumferential direction, the first grooves open to an outside, and having an opening space, a width of which is narrower than that of a bottom space thereof, and second grooves formed at a predetermined pitch therebetween on the outer surface of the tube body continuously along an axial direction, the second grooves having a depth shallower than that of the first grooves, and connecting opening spaces of adjacent first grooves to each other, wherein a projecting member is provided on a bottom surface of each of the first grooves so as to connect a side wall of each of the first grooves to another.
  • Fig. 1 is a partial perspective view of a heat transmission tube according to an embodiment of the present invention.
  • This figure shows a part of a tube body 10, in which fluid, i.e. water, coolant such as Freon, or vapor thereof, flows.
  • fluid i.e. water, coolant such as Freon, or vapor thereof
  • continuous second grooves 12 are formed also on the outer surface of the tube body 10 along the axial direction thereof (indicated by letter B in the figure).
  • a projecting member 15 for connecting a side wall 14 of one of the first grooves 11 to the same of another.
  • some of the examples of the raw materials for the tube body 10 are copper, steel, titanium, aluminum, and an alloy thereof.
  • Each of the first grooves 11 has a bottom portion 16 a width W1 of which is relatively wide, and an opening portion 17 a width W2 of which is relatively narrow.
  • the ratio of the width of the bottom portion 16 to that of the opening portion 17 (W1/W2) should preferably be in the range between 1 and 12 in consideration of follow-up for capturing and departure of bubbles.
  • a pitch P1 of the first grooves 11, that is, the distance between the centers of adjacent first grooves 11, should preferably be in the range between 0.5 mm and 1.0 mm in consideration of follow-up for capturing of bubbles and the heat transmissibility.
  • the number of the first grooves 11 should preferably be 25-50 per an inch, and they should be formed all the way through the heat transmission tube with an appropriate pitch P1 between each adjacent pair of the grooves.
  • a depth D1 of each of the first grooves 11 should preferably be in the range between 0.2 mm and 1.2 mm in consideration of follow-up for capturing of bubbles and the heat transmissibility. It should be noted here that as long as formed continuously in the circumferential direction of the tube body 10, the first grooves 11 may be ring-shaped, or spiral.
  • a pitch P2 of the second grooves 12, that is, the distance between the centers of adjacent second grooves 12, should preferably be in the range between 0.4 mm and 1.5 mm. This is because, if the pitch P2 is out of this range, the opening portion 17 cannot be formed to have desired measurements due to structural limitation.
  • the number of the second grooves 12 should preferably be 25-60 per an inch, and they should be formed all the way through the heat tube with an appropriate pitch P2 between each adjacent pair of the grooves. In order to generate more bubbles, the number of the opening portions 17 and the second grooves should be increased. It should be noted, however, that the number of these portions and grooves is somehow limited by the type of the fluid brought into contact with the outer surface of the tube body.
  • a height H of the projecting member 15 should preferably be 2-40% of the depth 1 of the first grooves 11. This is because, if the height H is less than 2% of the depth D1, the heat transmission tube cannot exhibit its full heat transmissibility in a low heat flux region, and if the height H exceeds 40% of the depth D1, supply of the coolant to the outer surface of the tube body is significantly reduced in a high heat flux region. Most preferably, the height H should be 10-40% of the depth D1. Further, as shown in Fig. 2, a pitch P3 of the projecting members 15, that is, the distance between the tip ends of adjacent projecting members should preferably be in the range between 0.5-4.5 mm.
  • the shape of the cross section of the projecting member 15 is not particularly specified here, and may be, for example, polygonal such as triangular, semicircular, or trapezoidal.
  • the heat transmission tube has such a structure that a projecting member 15 is formed on the bottom of each of the first grooves 11; therefore the area of the outer surface, which is called heat transmission area, with which the coolant is brought into contact, is larger than that without any projecting member.
  • the area of the outer surface, which is called heat transmission area, with which the coolant is brought into contact is larger than that without any projecting member.
  • each of the projecting members 15 serves to divide the bottom space of each of the first grooves 11 into small regions; therefore it becomes pos sible to suppress movement of the coolant at each proximal fin, that is, the bottom space of each of the first grooves.
  • coolant can be easily boiled by regional heating of the outer surface of the tube body; therefore the tube can exhibit a high heat transmissibility improved especially in a low heat flux region.
  • a copper tube having the external diameter of 19.05 mm and the thickness of 1.24 mm is subjected to a process with a disk 30 for formation of fins, disk 33 for formation of projecting members, tool 35 for formation of a second grooves, and rolling tools 36-39, as can be seen in Fig. 3.
  • the process of the tube body 31 is held by mandrel 41 in the tube and carried out starting from the state shown on the left-hand side of the figure toward the right-hand side.
  • the outer surface of the tube body 31 is formed into fins 32, and a projecting member 34 is formed on the bottom portion of each of the first grooves 40, each defined by adjacent fins 32, by means of a formation disk 33, on a part of the circumference of which teeth 33a are formed as shown in Fig. 4.
  • the tip of each of the fins 32 is gradually pressed to have thick head portion shown in the figure, and the second grooves are formed on the tube body 31 along the axial direction thereof by use of the rolling tube 35, in particular.
  • the tube thus obtained has forty of the first grooves 40 formed on each one-inch portion of the outer surface of the tube body 31 along the circumferential direction, a projecting member 34 formed on the bottom of each of the first grooves 40 along a direction substantially parallel to the axial direction of the tube body 31 such that the member 34 connect the fins 32 on both sides thereof to each other, and eighty of the second grooves formed also on the outer surface of the tube body along the axial direction thereof.
  • Each of each of the first grooves has the following measurements; the width of the bottom portion of 0.3 mm, the width of the opening portion of 0.1 mm, and the depth of 0.7 mm.
  • the pitch of the first grooves is 0.64 mm.
  • the pitch of the second grooves is 0.75 mm.
  • the height of the projecting members is 15% of the depth of the first grooves.
  • the pitch of the tip portions of the projecting members is 1.5 mm, and the cross section of each of the projecting members is essentially triangular.
  • Fig. 5 shows the boiling heat transmissibility (defined by the amount of heat transmitted, per unit length, unit time, and unit temperature) exhibited from a low heat flux region to a high heat flux region of each of the heat transmission tube of the present invention (characteristic curve 3), a conventional heat transmission tube with first and second grooves and without projecting members (curve 2), and a conventional heat transmission tube with low fin (26 per inch) (curve 1).
  • the heat transmission tube of the present invention exhibits a high boiling heat transmissibility in both low and high heat flux regions.
  • the transmissibility of the tube of the invention is 20% higher than that of the conventional tube (curve 2).
  • the projecting members 60 are formed such that the cross section thereof has a triangular shape as shown in Fig. 6B, but the shape of the cross section may be trapezoidal or semicircular as shown in Figs. 6A and 6C, without degrading the advantage of the invention.
  • the projecting members 60 are formed along a direction substantially parallel to the axial direction of the tube body, but as long as the projecting members connect both side walls of each of the first grooves to each other, they may be formed such that the longitudinal direction of the projecting members 70 is tilted with respect to the axial direction (direction C in Fig. 8) of the tube body by a predetermined angle less than 60° as can be seen in Figs. 7 and 8.
  • the heat transmission tube of the present invention has a high and stable heat transmissibility in both cases of low and high heat fluxes.
  • heat exchangers in which the heat transmission tube of the present invention is employed have advantages in terms of miniaturization of the device, as well as performance.
